Spring中Quartz的配置
Quartz是一个强大的企业级任务调度框架,Spring中继承并简化了Quartz,下面就看看在Spring中怎样配置Quartz:
首先我们来写一个被调度的类:
package com.yhcz.quartz; public class QuartzJob { public void work() { System.out.println("Quartz的任务调度!!!"); } }
Spring的配置文件:
<beans> <!-- 要调用的工作类 --> <bean id="quartzJob" class="com.yhcz.quartz.QuartzJob"></bean> <!-- 定义调用对象和调用对象的方法 --> <bean id="jobtask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <!-- 调用的类 --> <property name="targetObject"> <ref bean="quartzJob"/> </property> <!-- 调用类中的方法 --> <property name="targetMethod"> <value>work</value> </property> </bean> <!-- 定义触发时间 --> <bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail"> <ref bean="jobtask"/> </property> <!-- cron表达式 --> <property name="cronExpression"> <value>10,15,20,25,30,35,40,45,50,55 * * * * ?</value> </property> </bean> <!-- 总管理类 如果将lazy-init='false'那么容器启动就会执行调度程序 --> <bean id="startQuartz" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref bean="doTime"/> </list> </property> </bean> </beans>
测试程序:
package com.yhcz.quartz; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class MainTest { /** * @param args */ public static void main(String[] args) { System.out.println("Test start."); ApplicationContext context = new ClassPathXmlApplicationContext("quartz-config.xml"); //如果配置文件中将startQuartz bean的lazy-init设置为false 则不用实例化 //context.getBean("startQuartz"); System.out.print("Test end.."); } }
